Third Degree Atrioventricular Block

Abstract Background Modern permanent pacemakers (PPMs) have individual features designed to identify cardiac rhythm abnormalities and improve their performance. Inappropriate pacing inhibition may be an undesired outcome from these features and cause symptoms in patients who require frequent pacing, leading to dizziness, and syncope. Inappropriate inhibition can be difficult to identify in circumstances that are intermittent and difficult to reproduce. Case summary A 57-year-old female underwent a mitral valve replacement (MVR) for severe mitral stenosis. One month following MVR, she presented with symptomatic third-degree atrioventricular block, and a dual-chamber PPM (Advisa™, Medtronic, Minneapolis, USA) was implanted and programmed DDD 50–130 b.p.m. At the 3-month follow-up, she reported frequent episodes of lightheadedness. She was found to have intermittent ventricular pacing inhibition on a 48-h Holter monitor due to an internal function of the Advisa™ series of PPMs that attempts to store an electrogram (EGM) every 1 h and 30 s. During the EGM storage, an amplified signal from the storage capacitor can result in oversensing by the ventricular channel and inappropriate pacing inhibition. Discussion To rectify the issue, the ventricular lead sensitivity value was increased from 0.9 mV to 1.2 mV. No instances of inappropriate ventricular pacing inhibition were noted on follow-up. To our knowledge, this is a rare case of inappropriate ventricular pacing inhibition caused by a combination of PPM self-adjusting sensitivity algorithm and oversensing every 1 h and 30 s from an amplified storage capacitor. Physicians should be aware of this possible complication and differentiate it from device or lead malfunction.

Metadata Interoperability

Abstract A pidgin metadata framework based on the concept of pidgin metadata is proposed to complement the limitations of existing approaches to metadata interoperability and to achieve more reliable metadata interoperability. The framework consists of three layers, with a hierarchical structure, and reflects the semantic and structural characteristics of various metadata. Layer 1 performs both an external function, serving as an anchor for semantic association between metadata elements, and an internal function, providing semantic categories that can encompass detailed elements. Layer 2 is an arbitrary layer composed of substantial elements from existing metadata and performs a function in which different metadata elements describing the same or similar aspects of information resources are associated with the semantic categories of Layer 1. Layer 3 implements the semantic relationships between Layer 1 and Layer 2 through the Resource Description Framework syntax. With this structure, the pidgin metadata framework can establish the criteria for semantic connection between different elements and fully reflect the complexity and heterogeneity among various metadata. Additionally, it is expected to provide a bibliographic environment that can achieve more reliable metadata interoperability than existing approaches by securing the communication between metadata.

Indicators for Stress Adaptation Analytics (ISAAC) is a protocol to measure the emergency response behavior of organizations within local public health systems. We used ISAAC measurements to analyze how funding and structural changes may have affected the emergency response capacity of a local health agency. We developed ISAAC profiles for an agency's consecutive fiscal years 2013 and 2014, during which funding cuts and organizational restructuring had occurred. ISAAC uses descriptive and categorical response data to obtain a function stress score and a weighted contribution score to the agency's total response. In the absence of an emergency, we simulated one by assuming that each function was stressed at an equal rate for each of the two years and then we compared the differences between the two years. The simulations revealed that seemingly minor personnel or budget changes in health departments can mask considerable variation in change at the internal function level.

Cryptographic Hash Functions

The purpose of this article is to construct an internal function underlying the “Sponge” scheme for constructing  cryptographic  hash  functions.  An  internal  function in  the  “Sponge”  scheme  is  a  fixed-length transformation  or  permutation  that  operates  on  a  fixed  number  of  bits  that  make  up  the  internal  state  of  the function. There are various constructive approaches to functiondesign. The most common approach is to use a permutation based on a symmetric block encryption algorithm with constants as the key. This article builds an internal  function  using  the  generalized  AES  design  methodology. This  methodology  makes  it  easy  to  design block  ciphers  to  encrypt  large  blocks  of  plaintext  with  small  components,  representing  the  processed  data as  multidimensional  arrays.  The  internal  function  is  a  block  cipher  that  processes  2048  bits,  represented as  a  9-dimensional  array  of  512  4-bit  elements  with  size  2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2.  Each  round of encryption  consists  of  three  transformations  (S-blocks,  linear  transformation,  and  permutation),  similar  to the three round transformations of AES SubBytes, MixColumns, and ShiftRows. The constructed function can be used as an internal function in the modified “Sponge” schemefor constructing cryptographic hash functions.

Perception Of Innovation

The contents of the chapter refer to innovations in organizations and particularly as their perception processes are implemented. At this point, the role and importance of academic institutions is more likely to be discussed as the internal initiatives for academia are concerned. The main objective of the work was to obtain the systematic approach to the issues of university transformation to such a point that the need of innovativeness at universities is discussed. This is compared against the requirements of stakeholders. The need for solutions is a normative issue, as expected by stakeholders. However, the issue of implementing innovative solutions is a topic of scientific discussion that is closely related to innovation, and which at the same time outlines a new dimension of perception of innovation in both business units and scientific units. Considerations can be made that implementation is the internal function of innovation that verifies in proportion to the radicalism of innovation the possibilities of their practical application.
